sup guys...need some help. I'm ordering an HKS Carbon Ti catback in a day or so. I also want to go ahead and pick up an HKS dp, and high flow cat. if i go that route, who makes good cats? i am also kicking around the idea of just going with no cat. if i do that, what DP's do u suggest that delete the cat? also, will it be much louder with no cat, than with one?

 

anybody?

 

People seem to like the Helix HFC. You can also look at the WORKS HFC which looks more like a stock cat. Or the WORKS StealthCat which is a stock cat with new 3" flanges. I don't like the Helix one because it's too shiny for me. Although it's really pricey, I have a StealthCat on order since I don't want to run into any trouble with the police.

 

i just put the helix in, the fitment was ok. Flow seems to be pretty good and its not as loud as a test pipe.

 

I run the ultimate racing 3" hi flo cat. Fits just like stock and has never triggered a CEL in over 6k miles.

 

cool, thanks. are test pipes really loud on our cars? i know on N/A cars they are, but i've always heard turbo's make good mufflers

 

Ultimate Racing makes great cats and test pipes. I have a cat for emissions testing and a Test pipe for the rest of the year. I got mine from Adam at Z-1 Perfromance check out the link. http://www.z1auto.com/prodmore.asp?m...ust&prodid=481
